Expression of human phosphatidylethanolamine-binding protein 4 in patients with multiple myeloma and its significance / 白血病·淋巴瘤

Objective:To investigate the expression of serum human phosphatidylethanolamine-binding protein 4 (hPEBP4) in patients with multiple myeloma (MM) and its clinical significance.Methods:A total of 59 symptomatic MM patients admitted to West Branch of Beijing Chaoyang Hospital from September 2016 to September 2018 were selected as the research objects. According to the CRAB symptoms [elevated serum calcium (C), kidney injury (R), anemia (A), bone lesions (B)], all patients were divided into 2 groups, including the active group of 44 patients with CRAB symptoms, and the response group of 15 patients who achieved at least partial remission after chemotherapy and symptom relief of CRAB. According to the degree of bone lesions (BL), 30 patients with severe bone-related events were grouped as the severe bone lesions (SBL) group, and 14 patients were grouped as the non-severe bone lesions (NSBL) group. According to the revised international prognostic staging system (R-ISS), patients in the active group were divided into three subgroups: stage Ⅰ, stage Ⅱ, and stage Ⅲ, including 26, 11 and 7 patients, respectively. A total of 15 healthy examination people whose gender and age matched those of the patients were treated as the healthy control group. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression levels of hPEBP4, tumor necrosis factor ligand superfamily member 14 (LIGHT/TNFSF14) and activin A of patients in different groups. Pearson was used to analyze the relationship of the expressions of multiple factors in the active group. The optimal cut-off value of multiple factors diagnosing MM was determined by using receiver operating characteristic (ROC) curve, and according to the cut-off value, the differences in overall survival (OS) of patients with different stratification were compared.Results:In the active group, the respond group, the healthy control group, the level of hPEBP4 was (1.48±0.64) μg/L, (1.49±0.75) μg/L, (0.31±0.10) μg/L, respectively; the level of LIGHT/TNFSF14 was (169±112) ng/L, (256±132) ng/L, (44±27) ng/L,respectively; the level of activin A was (383±266) ng/L, (223±79) ng/L, (234±85) ng/L, respectively; and the differences were statistically significant (all P<0.05). In the active group, the level of hPEBP4 was (1.06±0.60) μg/L, (1.15±0.50) μg/L, (1.73±0.68) μg/L, respectively in patients with stage R-ISSⅠ, R-ISSⅡ and R-ISS Ⅲ, and the difference was statistically significant ( F=3.287, P=0.032). The level of activin A was (219±55) ng/L, (247±117) ng/L, (450±215) ng/L, respectively among patients in stage R-ISSⅠ, R-ISSⅡ, R-ISS Ⅲ, and the level of activin A in stage R-ISS Ⅲ was higher than that in stage R-ISSⅠand R-ISSⅡ (all P < 0.05). The levels of LIGHT/TNFSF14 and activin A of SBL patients were higher than those of NSBL patients [(174±101) ng/L vs. (98±53) ng/L; (467±238) ng/L vs. (189±71) ng/L, all P < 0.05]. The level of hPEBP4 was positively correlated with the levels of M protein ( r=0.694, P < 0.01) and activin A ( r=0.252, P < 0.01) of IgG patients in the active group. ROC curve analysis showed that the optimal cut-off value of hPEBP4, LIGHT/TNFSF14, activin A diagnosing MM was 1.04 μg/L, 97.0 μg/L, 156.2 ng/L. The median overall survival (OS) time of patients with hPEBP4 >1.04 μg/L and hPEBP4 ≤ 1.04 μg/L was 57 months (95% CI 22-92 months) and not reached, respectively, and the difference was statistically significant ( P < 0.05); while the median OS time of patients with activin A ≥ 156.2 ng/L and activin A < 156.2 ng/L was 61 months (95% CI 24-98 months) and not reached, respectively, and the difference was statistically significant ( P < 0.05). Conclusions:High expression level of hPEBP4 is related with the progression of MM. It is positively related with the level of M protein and negatively with the OS of MM patients. It is suggested that hPEBP4 may be used as an important marker to judge disease progression and tumor burden in MM. LIGHT/TNFSF14 and activin A cooperate with hPEBP4 to participate in the pathological processes of tumor microenvironment of MM.

The 474th case: anemia, ostealgia, proteinuria / 中华内科杂志

A 49-year-old woman was admitted to hospital with intermittent dizziness and fatigue for 7 years. The symptoms were aggravated and accompanied by bone pain for more than 4 months. She was referred to our hospital. Laboratory tests and imaging findings suggested that acquired Fanconi Syndrome (FS) was associated with smoldering multiple myeloma (MM). Renal biopsy and electron microscopy confirmed the diagnosis of proximal light chain tubular disease (LCPT). LCPT causes proximal tubular dysfunction, which is characterized by the cytoplasmic crystal deposition usually kappa monoclonal light chain in the proximal tubule. MM with FS and LCPT is less common in clinical practice because it is difficult to diagnose. This is a typical case focusing on the differential diagnosis of monoclonal gammopathy of renal significance(MGRS) such as LCPT and plasma cells diseases.

A clinical analysis of 69 newly diagnosed multiple myeloma patients with renal insufficiency / 中华内科杂志

Objective To investigate the efficacy and outcome in newly diagnosed multiple myeloma (MM) patients with renal insufficiency using bortezomib-or thalidomide-based regimens as front line treatment.Method Sixty-nine newly diagnosed MM patients with renal insufficiency were retrospectively analyzed from August 2006 to August 2014.Results ① Among thirty-nine patients with bortezomib based regimens (the bortezomib group),the overall response rate (ORR) was 89.7％ and complete response (CR) plus near CR(nCR) rate was 41.0％.By contrast,among thirty patients with thalidomide based regimens (the thalidomide group),the ORR was 83.3％ and CR + nCR rate was 26.7％.There was no significant difference of either ORR or CR + nCR rate between bortezomib and thalidomide groups.② The improvement rate of renal function in bortezomib group and thalidomide group were 87.2％ and 60.0％respectively (P =0.012).The median duration time of renal injury was 45 days in 52 patients with renal function improved,which was significantly shorter compared with 222 days in 17 patients without improvement (P ＜ 0.05).There was no difference of median serum creatinine and creatinine clearance rate between the two groups.③ The median progression-free survival (PFS) and the overall survival (OS) were 18 and 33.5 months,respectively in all patients.The three-year and five-year OS rates were 57％ and 17％,respectively.The median PFS was 19 months in bortezomib group,while it was only 12 months in thalidomide group (P =0.023).The median OS were 36.5 months and 25.5 months respectively,which was no difference (P =0.285).Conclusions The newly diagnosed MM patients with renal insufficiency could get higher ORR and the longer PFS using bortezomib-containing regimens as initial therapy.Meanwhile the improvement rate of renal function and the living quality in patients with bortezomib are better compared with those with thalidomide based treatment.

Clinical analysis of early death in multiple myeloma / 中国肿瘤临床

Objective:This study investigated the clinical characteristics of multiple myeloma with early death in the era of novel drugs. Methods:Medical records from 188 patients diagnosed from January 2009 to December 2015 were retrospectively reviewed, showing that early death occurred in 19 patients. Early death was defined as death by any cause within the first year after diagnosis. Results:(1) Early mortality was 10.1%, and the median age was 67 years old (range:40-84 years). Eight cases presented IgG type, and 11 cases were non-IgG type. All 19 patients were diagnosed to be at stageⅢin accordance with the Durie–Salmon staging system, and renal insufficiency occurred in 10 patients. In accordance with the International Staging System (ISS), four patients were diagnosed to be at stageⅡ, whereas 15 other patients were at stageⅢ. Extramedullary plasmacytoma (EMP) occurred in six cases, whereas 10 cases pre-sented high-risk patients with cytogenetic abnormalities. Elevated lactate dehydrogenase (LDH) was found in five cases, amyloidosis was detected in three patients, and secondary plasma cell leukemia was observed in two cases. The median score of performance sta-tus (KPS) was 70 (range: 20-80). A total of 16 patients were treated with bortezomib, and 3 patients were treated with CADT. (2) Among the 13 patients who were evaluated, the overall response rate was 46.2%(6/13), and the complete response (CR) and near-CR rate was 7.7%(1/13). (3) The median overall survival was 3 (1-11.5) months, although the two patients with secondary plasma cell leu-kemia survived for less than 2 months. (4) Eight patients died of disease progression (42.1%), eight patients died of severe infections (42.1%), and three patients died of thrombotic events. Conclusion:The important causes of early death include the following:high-risk cytogenetics, elevated LDH, EMP, amyloidosis, advanced age, poor performance status, and serious complications during treat-ment. In the era of novel drugs, we should improve early diagnosis rates and explore individualized treatment for high-risk multiple my-eloma for the benefit of a wide range of patients.

Impact of 1q21 amplification on prognosis and treatment effect of multiple myeloma / 白血病·淋巴瘤

Objective To investigate the value of 1q21 amplification in newly diagnosed myeloma patients.Methods Fifty-two cases of newly diagnosed multiple myeloma from June 2008 to June 2010 were enrolled.Fluorescence in situ hybridization (FISH) was used to detect the 1q21 amplification,and the clinical characteristics and treatment response were analyzed.Results 1q21 amplification was discovered in 30 of 52 patients (57.7 ％),Clinical characteristics such as gender,malignant pleural effusion,extramedullary plasmacytoma,bone destruction,β2 microglobulin,ALB,hemoglobin,blood calcium,plasma cell proportion,clinical stage seemed to have no correlation with 1q21 amplification.The 52 patients all received bortezomibbased regimens.The response rates were not significant difference between patients with and without 1q21 amplification,the OS was also not significant difference [26 months (6-30 months) vs 30 months (12-85 months),P =0.409],but the patients with presence of 1q21 gain resulted in significantly shorter PFS [8 months (1-30 months) vs 20 months (3--48 months),P=0.019].Multivariate analysis showed 1q21 with more than two additional genetic abnormalities was an independent prognostic predictor (P =0.031).Conclusion 1q21 amplification is one of the adverse prognostic predictors,the response rate is not significant difference between patients with and without 1q21 amplification in bortezomib-based group,but the 1q21 amplification could result in significantly shortened PFS.

Sequential therapy of BTD and MPT regimen for the newly-diagnosed multiple myeloma patients no eligible for bone marrow transplantation / 白血病·淋巴瘤

Objective To retrospectively analyze the outcomes and adverse effects of sequential therapy of BTD and MPT regimen for the newly-diagnosed multiple myeloma patients no eligible for high dose chemotherapy and stem cell transplantation. Methods Thirty-six patients were involved in this study and the patients were treated with tandem therapy of BTD and MPT regimen. The patients were treated with BTD regimen as induced therapy no less than 2 cycles. When the patients got PR or above PR,they were treated with MPT regimen as consolidation therapy which was no less than 2 cycles. Then,the patients who achieved PR or partial PR were received MPT chemotherapy regimen as consequent treatment. After that,low dose thalidomide was used as maintenance therapy. The outcomes and adverse effects were retrospectively evaluated. Results Thirty-six patients were treated with BTD regimen as induced therapy. The results were that 7 patients (19.4 %) achieved CR,8 (22.2 %) VGPR,14 (38.9 %) PR and the OR rate was 80.6 %. The patients (n=29) who achieved no less than PR was treated with MPT regimen as consequent therapy. The results were that four patients were in progression and the others were stable. Twenty-five patients were treated with low dose thalidomide as maintenance therapy. The median progression-free survival (PFS) did not reached yet until last follow-up (median follow-up time was 16.5 months). One-year overall survival rate was expected 86.0 % and 3-year expected overall survival rate was 77.0 %. The main regimen-associated toxicities included thrombocytopenia,peripheral neuropathy (PN),Herpes Zoster,gastrointestinal symptoms,anemia,neutropenia,constipation,fatigue,rash and so on. The incidence of grade 3 and 4 adverse events was low. Conclusion Sequential therapy of BTD and MPT regimen can be used as the front-line therapy for the newly-diagnosed multiple myeloma patients no eligible for high dose chemotherapy and stem cell transplantation.

Effectiveness of lenalidomide-based chemotherapy on 25 patients with multiple myeloma / 白血病·淋巴瘤

Objective To evaluate the efficacy and safety of lenalidomide(Len)-based regimens in the treatment to patients with multiple myeloma (MM). Methods Twenty-five multiple myeloma patients who received Len-based regimens were enrolled in this study. There were 5 newly-diagnosed MM patients, 13 relapsed/refractory (rel/ref) MM and 7 MM patients at plateau after treatment. The newly-diagnosed patients received R-PAD regimen, rel/ref MM received R-MD and the patients at plateau(maintenance treatment group) due to more than 2 grade peripheral neuropathy (PN) received Len monotherapy. Results All of the five newly-diagnosed MM achieved complete remission (CR) (100 %) after 2 courses of theatment; of 13 rel/ref patients (76.92 %) achieved overall response, including 3 (23.08 %) achieving CR, 2 (15.38 %) very good partial response (VGPR), 5 (38.46 %) partial response (PR) and the overall response rate was 76.92 %. Two of the other three no response patients had stable disease(SD) and one had progress disease(PO). The seven patients in maintenant treatment group maintained remission in an average follow-up period of 38 weeks and their PN was relieved in various degrees. Conclusion R-PAD regimen is a highly active regimen for newlydiagnosed MM and R-MD regimen is a promising regimen for rel/ref MM, especially for the patients with serious PN; Len may be a good choice as maintenant chemotherapy for the patients with PN.
